S197 Mustang (2005-2010)
I put the order in today... $241.49 shipped.
1. GTA's - too quiet, too fragile (hanger welds kept breaking)
2. 5GT's (aka Stingers) - EXCELLENT sound both at idle and WOT. Drone at highway speeds drove me N-V-T-S nuts...
Had a set of Dynomax resonators installed into the over axle pipe...
